Separation type airflow drying kettle

Abstract

The invention discloses a separation type airflow drying kettle. The drying kettle is a cylindrical shell, and a cylindrical drying cylinder is arranged in the middle of the shell; a rotating shaft is arranged on the top of the drying cylinder and is fixedly connected to a transmission motor, and the side wall of the drying cylinder is composed of a filtering screen; two perpendicular blast pipelines are arranged on the inner wall, the same as the drying cylinder in height, of the shell, and a plurality of air outlets are evenly distributed in the positions, with the different heights, of the blast pipelines; an air inlet pipeline is arranged on the outer side of the shell and is connected to the blast pipelines, and a light-material collecting opening and a heavy-material collecting opening are formed in the bottom of the shell; and the heavy-material collecting opening is fixedly connected to the bottom of the drying cylinder through an extending pipe and a rotating bearing. Through double effects of airflow and centrifugal force, the problem that damp materials are stuck to the filter screen is solved, and meanwhile, the materials in the drying cylinder can be separated; and the small-particle materials are discharged out of the drying cylinder along with the airflow or under the effect of the centrifugal force, and the materials with different masses or volumes can be conveniently collected.

Description

technical field [0001] The invention relates to the field of material drying equipment, in particular to an airflow drying kettle that can facilitate material separation. Background technique [0002] The main principle of the airflow drying kettle is to dry the material through the airflow, and take away the moisture in the material through the high temperature and airflow, so as to promote the rapid drying of the material. In the actual operation process, because the wet material is generally stored with a screen, the wet material It is easy to accumulate in the screen holes of the screen, which not only affects the ventilation effect of the screen itself, but also reduces the drying efficiency of the device. At the same time, the dried materials are easy to block the screen opening, making it difficult to clean and collect. [0003] At the same time, for the ordinary airflow drying kettle on the market, its function is relatively single, and it can only be used for the dr...

Problems solved by technology

[0002] The main principle of the airflow drying kettle is to dry the material through the airflow, and take away the moisture in the material through the high temperature and airflow, so as to promote the rapid drying of the material. In the actual operation process, because the wet material is generally stored with a screen, the wet material It is easy to accumulate in the screen holes of the screen, which not only affects the ventilation effect of the screen itself, but also reduces the drying efficiency of the device. At the same time, the dried materials are easy to block the screen opening, making it difficult to clean and collect.

[0003] At the same time, for the ordinary airflow drying kettle on the market, its function is relatively single, and it can only be used for the drying operation of materials; but because there are large particles of materials and small particles of materials in the dried materials, the weight and volume of these materials are different. , leading to different uses after drying; at the same time, small particles of materials are easy to move with the movement of the airflow during the airflow drying process, which is inconvenient to collect and brings great troubles to the operators.
